Ovarian maturation stages of the wild giant tiger prawn, Penaeus monodon Fabricius
(Elsevier, 1989)
A qualitative and quantitative study of the ovarian maturation stages of wild-caught Penaeus monodon was conducted to refine the existing method of staging. For industrial purpose, measuring the ovarian width at the first ...
The effect of stress on spawning of brood fish and survival of larvae of the rabbitfish, Siganus guttatus (Bloch)
(Elsevier, 1989)
The effects of stress due to handling, and repeated sham and human chorionic gonadotropin (HCG) injections on spawning and survival of the rabbitfish, Siganus guttatus were studied. Results showed that stress significantly ...
Effect of tagging on maturation and survival of ablated Penaeus monodon in painted and unpainted tanks
(San Carlos Publications, University of San Carlos, 1989)
A study was conducted to determine the effects of tags and tank color on reproductive performance and survival of pond-reared Penaeus monodon after eyestalk ablation. In 1986, the best over-all reproductive performance was ...
Use of kappa-carrageenan microbound diet (C-MBD) as feed for Penaeus monodon larvae
(Springer Verlag, 1989)
The performance of an artificial practical diet, kappa-carrageenan microbound diet (C-MBD) was assessed on Penaeus monodon larvae at the SEAFDEC Broodstock and Maturation Experimental Laboratory in March 1986. Shrimps were ...
Comparison of various water replenishment and fertilization schemes in brackishwater milkfish ponds
(Blackwell Publishing, 1989)
The study was undertaken to determine the optimum combination of the frequency of water replenishment and fertilization that can yield the highest growth, survival, and gross production of milkfish. Results indicated that ...
Tolerance level and histopathological response of milkfish (Chanos chanos) fingerlings to formalin
(Elsevier, 1989)
Static 96-h bioassays were conducted on milkfish (Chanos chanos ) fingerlings with formalin at concentrations ranging from 50 to 500 ppm. The 24-, 48-, 72-, and 96-h median lethal concentration values (LC50) were 322, 260, ...
HCG and LHRH-A induced spawning in bighead carp Aristichthys nobilis Rich. reared in floating cages in Laguna de Bay
(San Carlos Publications, University of San Carlos, 1989)
Hormone-induction of spawning in bighead carp Aristichthys nobilis Rich. by single or double intraperitoneal injection with varying combined dosages of HCG and LHRH-A was conducted. Fish were spawned successfully following ...
Effect of storage temperature on the quality of diets for the prawn, Penaeus monodon Fabricius
(Elsevier, 1989)
The effect of storage temperature was evaluated on the basis of growth response of prawns fed for 10 weeks with diets stored at 0°C, 10°C, 28°C-31°C (ambient temperatures) and 40°C for a period of 10 weeks. Prawns were ...
Preliminary results of feeding aquatic macrophytes to Penaeus monodon juveniles
(Elsevier, 1989)
Penaeus monodon juveniles (PL<sub>50</sub>) were fed live and decaying aquatic macrophytes and a commercial grow-out pellet (40% crude protein) in 80-l glass tanks over a 30-day period. Growth and survival were significantly ...
Acute toxicity of potassium permanganate to milkfish fingerlings, Chanos chanos
(Springer Verlag, 1989)
Potassium permanganate (KMnO<sub>4</sub>) is a strong oxidizing agent and is commonly used in aquatic systems to improve available oxygen, treat infectious diseases and parasites, detoxify fish poisons, and control algae. ...
